Abstract
A 2 pole bearingless interior permanent magnet (IPM) motor with slice rotor configuration is presented in this paper. A novel IPM rotor is designed considering various specifications such as force constant, torque constant and cogging torque. Cogging torque and resulting vibrations affects the motor and levitation operation significantly. Since the cogging torque is a result of the motor geometry, finite element (FE) simulation is used to simulate various rotor geometries to find the desired rotor configuration. FE simulations are also used to obtain other parameters like force and torque constant, and magnetic stiffness for designing control. The final design is fabricated and tested for closed loop levitation control and speed control. The simulation results and experimental control system performance is shown and explained in the paper.
